Scripts for deploying the Virtual Map Forum 2.0

This repository contains the configuration files and ansible scripts for deploying the different service of the Virtual Map Forum 2.0.

Placebook	Purpose	Requirements
core_setup/main.yml	Installs a base system with the user "vk2adm", blocks the "root" user for ssh and configures IP tables with open ports for SSH and HTTP/S	Debian 11 SSH-Login for User root via key file
service_basemap/standalone_basemap.yml	Installs a standalone tile server with initial configuration and an Apache2 HTTP server as reverse proxy and image cache.	Debian 11 SSH-Login for User vk2adm via key file core_setup/main.yml was executed before at least 2 cpu cores at least 2 gb ram at least 40 gb disk space for default configuration

Recommendation for service dimensioning

The Virtual Map Forum consists of a number of different services, which can be dimensioned and configured in different ways.

The following dimensioning is recommended as a standard setup.

Domain / Name	Purpose	Requirements	Redundancy
internal-tile-{x}.slub-dresden.de	Tileserver delivering raster and vector tiles based on an OpenStreetMap dump. In case the server are set behind a load balancer the domains should be used by the load balancer.	Debian 11 2 cpu cores 2 gb ram 120 gb disk space	At least 2 server. In case of high parallel load of raster tiles 3 to 4 would be better.
tile-{1|2|3}.slub-dresden.de}	Load balancer based on Apache2 HTTP server. Distributes tile requests across multiple servers.	Debian 11 1 cpu cores 2 gb ram 20 gb disk space	Not necessary.
